SPECIFICATION forming part of Letters Patent No. 378,295, dated FebruaryZl, 1888. Application filed December 21, 1887, Serial No. 258,562. (No model.)

To all whom it may concern.-

Be it known that I, HERMAN DOERING, a citizen of the United States, residing at Reedsburg, in the county of Sank and State of Wiscousin, have invented certain new and useful Improvements in Stitchingllorses, of which the following is a full and clear description, reference beingbad to the accompanying draw lugs, forming part of this specification, in which- Figure 1 represents a perspective view of a stitching-horse embodying myinvention. Fig. 2 is an elevation, partly in section, showing one of the side plates removed. Fig. 3 is a detail of the casting L. 1

My invention relates to that class of ma chines for stitching leather articles-such as harness-and commonly known to the trade as stitchinghorses, and my invention consists in the improved constructions and combina' tions of devices which I shall hereinafter fully describe and claim.

To enable others skilled in the art to make and use my invention, I will now describe the same and indicate the manner in which the same is carried out.

In the said drawings, A represents a suitable frame, comprising the supporting-legs a, the scatb, and the rock-shaft c. The seat portion b is provided with a curved recess, :2, in the center of which an opening, 6, is formed, and on the upper surface of said seat, contiguous to the recess (1, are secured castings having horizontal arms,by which they are secured to said seat, and vertical arms gdhrough which bolts are passed.

In shoulders 0, formed in the seat on each side of the recess (Z, are vertically-arranged side pieces, 13, having slotted lower ends, through which the bolts 71 pass to secure said slde pieces, and to permit their vertical adj ustment to increase or lessen the height of the machine.

The jaws C, between the faces of which the leather or other material to be sewed is placed, are provided with inwardly-extending lugs a, through which and the upper ends of the side pieces, 13, a bolt, D, is passed, thereby form ing a hinge-connection for saidjaws, said bolt hinged or otherwise pivotally connected. p

These levers extend in opposite directions and are acted upon by a spring, F, coiled around a bar, k, between the side pieces, B, having one end hearing against one of the levers E and its opposite ends secured in the opposite lever, B. 4

The lever E is formed with two parallel long arms, at, and the lever E is provided with a single long arm, a, which passes between the arms of the opposite lever, while the lower ends of both levers are attached to a strap or connection, G,which passes therefrom through openings 1') in the ends of the recess 1), and is connected with a foot-lever, H, pivoted to the rock-shaft c, and provided with a pawl, 0, adapted to engage a rack, 2, secured to one of the legs a.

Just below the jointed connection with the jaws G the lovers are provided with inwardlyextending lugs I, through which a bolt, 9', is passed to form a hinge, whereby the upper ends of the levers E E are held together. The bolt which passes through these lugs I also p rojects into elongated slots 8 in the upper portions of the side pieces and playsloosel y therein, to provide for the necessary movement of the upper or short arms of said levers.

In each end of the recess b, contiguous to the openings b, is secured a. bracket, L, having upwardly-extending lugs 2?, between which a roller, a, is loosely mounted, and over these rollers the strap G passes after leavingthc end of the lovers E E. It will thus be seen that upon depressing the foot-lever H the strap or connection draws the lower ends of the levers E E outward and causes the upper or short arms of said levers to force the lower short arms, C, of the jaws G outward, thereby closing the gripping-faces of said jaws tightly against the material or article to be operated upon. After the jaws are closed the foot-1ever H is moved laterally, so that its pawl will engage the rack 12, and thereby hold the sevcral parts in a closed position.

To release the article or material between the jaws, the operator simply moves the footlever out of its engagement with the rack, when IOU the spring F, acting upon the lopgar ns of the levers EE, causes thegripping-faces of the jaws to separate by a movement the reverse of that just described.

5 Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. The combination, with the frame A, provided with the seat-frame, the operating foot- 10 lever, and the rock-shaft, of the vertically-adj ustable side pieces, the crossed levers pivoted together between said side pieces, the jaws G, pivoted together and to the short arms of the levers, and a strap or connection between the I 5 lower ends of the levers and the operating footlever, substantially as described.

2. The frame A, having the recessed seat portion, the foot-lever, and the rock-shaft, in combination with the slotted side pieces, the 20 lugs and bolts by which they are vertically adjusted, the levers E'E, pivoted together and ov es n oppos t direct ons. esp 12m a n upon the long arms of said levers, the jaws pivoted together and having their short arms pivoted or hinged to the short arms of the levers, and the strap-connection between the levers and foot-lever, and a holding pawl and,
